NHTSA Complaint #11715259 — 2023 GRAND DESIGN SOLITUDE

This report details a suspected major structural frame failure on my 2023 Grand Design Solitude 391DL. The issues, which are progressive and worsening, indicate a severe loss of structural integrity in the front gooseneck and upper deck area of the fifth wheel. Key observations and symptoms include: Interior Wall Deformation: Interior wall panels in the front bedroom are visibly buckling and warping under stress. Separation of Wall Panels: The rear wall panel inside the main bedroom closet has developed a significant gap and is separating, believed to be a direct result of excessive frame flex. Misalignment of Door Frames: The door frame for the front closet housing the washer and dryer has spread apart to the point where the door can no longer latch or close properly. This demonstrates a clear deformation of the coach's superstructure. Audible Structural Noise: The floor in the front bedroom section produces constant, loud creaking and groaning sounds when walking on it, consistent with a compromised frame and subfloor structure. Safety Concerns: The progressive nature of these failures raises significant safety concerns regarding the vehicle's roadworthiness. The loss of structural integrity in the gooseneck area could lead to a catastrophic failure while the vehicle is in motion, posing a severe risk of detachment, loss of control for the tow vehicle, and danger to other motorists. The integrity of critical components like the roof, slide-outs, and heavy appliances is also compromised. This issue appears to be consistent with a pattern of similar frame-related failures reported by other Grand Design owners, which are the subject of an ongoing class-action lawsuit. I urge the NHTSA to investigate this critical safety defect before it results in a major highway incident.
